Is your android mobile phone often overheating or the battery draining faster than normal? There are chances that your mobile phone is infected with a malware that will use your phone to generate money for cyber criminals.

Researchers at Lookout have spotted a new piece of malware targeting android devices on some spanish forums that distributes pirated software.

This malware, referred as 'CoinKrypt', is not designed to steal any information from the infected devices. However, that doesn't mean that it is not harmful. It will use the maximum computation power of your device to generate virtual currencies.

It will result in the infected device getting overheated and will affect the battery life.

The malware appears to be targeting only newer virtual currencies such as Litecoin, Dogecoin, Casinocoin. Since, one will need high computing power to generate the popular and most valuable virtual currency 'Bitcoin', the cyber criminals didn't include the bitcoin mining process in this malware.

At this time, it is almost one million times easier to mine Litecoin than Bitcoin and over 3.5 million times easier to mine Dogecoin. Even though these newer coins are not as valuable as Bitcoins(1BTC is around $650, 1LTC is reaching $20), cyber criminals are probably hoping that one day they will reach high value like Bitcoins.

Dogecoin, a virtual currency described as potential successor to the Bitcoin, has been hacked and 21 million coins stolen from the DogeWallet.

The value of Dogecoin is very low comparing to Bitcoin. The current value is around $0.0057, means the coins lost in the heist are equivalent to about $12,000.

After analyzing the logs, they found that hacker gained to their filesystem and modified the send/receive page to send to a static address.

"We're incredibly sorry to all users who lost funds from the attack. Please use offline wallets as online wallets are meant for new users who aren't using them as a storage of coins" Reddit post suggest users to use offline Wallets.

"Offline wallets are more safe and secure than any online wallet due to possible attacks that can originate from anyone, anywhere."

Dogecoin promised to refund all lost coins. However, they said in a reddit post that "refunding temporarily halted in the meantime. Even though millions of dogecoins have been returned, there's a lot of users will smaller amounts of Doge that need to be refunded."

The Reserve Bank of India(RBI) has issued a warning against the use of Virtual currencies such as controversial Bitcoin saying that they poses a potential financial, legal and security related risks.

RBI warned in its press release that creating, trading or using any of virtual currencies including Bitcoin, Litecoins, bbqcoins, dogecoins are not authorized by any central bank or monetary authority.

RBI said since the virtual currencies are stored in digital form(electronic wallets), they are prone to losses arising out of hacking, loss of password, compromise of access credentials, malware attack.

The warning comes few days after Chinese government banned the use of Bitcoin in their countries Banks, pointing out the risks of using Virtual Currency.

Earlier this month, the French Central Bank also issued a warning about the Bitcoin transaction.

Bitcoins are highly Unstable, the Price keeps going up to $1100 and then it crashes back one nite to $700 and again climbs to $1100, then again drops with negative news. Looks like buying has been more of speculative nature.

Is it worth mining:

Depends on what price you get the miners. Most of people who are benefitting are people who are talented to make the miners(and sell hashfast.com, BFL labs(butterfly labs).

The bulls are brilliant as they know what to do with the money they make. They rotate it, sell it on ebay/paypal or buy from one exchange and sell on other exchange which gives them more return. they resort to trading to improve the money.

There is a pump and dump scam going on, which leads them to pump it falsely and then dump.

In long run the above methods removes the trust on bitcoin and eventually the bitcoins will crash. Computer programmers/hackers/technologist should protect the bitcoin and not go greedy about it.

We evaluated some of the mining:

a. cloudhasing.com - Cloud mining for bitcoins. contracts are so costly like 1 Ths cost around $20,000 (for a one month pre-order booking). Now when we computed the amount of money you make at current exchange rate. First month you make good money like $10,000 as the difficulty increases(around 15% every month) the amount of machine you need is close to 20% every month to make the same money.

cloud providers also take management fee, contract payment fee, electricity - Cooling. So eventually you make only 50% of actual BTC which is made. So it actually takes around 5 months to recover your investment with all exchange rate, mining difficulty(maintained at 15% per month). If exchange rate for Bitcoin does not increase regularly then its not worth. After china talked about bitcoin , bitcoin has crashed with not much buyers. If there is negative news from india, US...most of bitcoin exchange rate would fall and there would be no takers.

Cloud mining companies out of greed are retaining the bitcoin (they earn from buy orders) and they will go backrupt eventually. One of the provider takes money 4 months in advance for cloud minning of BTC. by the time the contract comes its not worth.

b. Grouphashing(announced) contracts for mining litecoin. It is not worth. You spend 1Mhs - 1.2BTC for a year contract which is close to $800 in todays rate. Takes you 50 Litecoin in today exchange rate to buy. You may make 0.4 litecoin a day.

c. CEX.io is too costly and not worth the returns.

d. Miners like KNC - 3 Ths are better bet if they deliver on time after 3 months.

Bitcoin is a gambling. if Exchange rate constantly goes up, Mining difficulty increases drastic because every one wants to get into it. If exchange rate for BTC falls, mining difficulty decreases. The net money you make as investor is not really worth after all the pain.

The exchanges in india like BuysellBTC closes half the days. when you want to sell(price is high-they are shutdown) because they dont want to pay you. when its BTC rate is low, they close down because they dont want to sell you at low rate :) . So even if you make profit you wont get in hand.
